This standard is part of the ISO 14122 series, intended to be used in conjunction with (which defines general requirements for access), and is essential for adhering to the European Machinery Directive (2006/42/EC). Scope of the Standard The standard applies to:
One notable correction in the German edition is that an error in the ISO version – where subclause number 8.2.2 was erroneously assigned for both “Loads” and “Testing procedure” – has been corrected in the German translation. This attention to detail is one reason why the DIN EN version is often preferred by German‑speaking engineers.
The standard distinguishes its access methods primarily by the angle of pitch ( : Pitch angles between 20∘20 raised to the composed with power 45∘45 raised to the composed with power Step Lenders : Pitch angles between 45∘45 raised to the composed with power 75∘75 raised to the composed with power din en iso 14122-3 pdf
Guard-rails are mandatory when the risk of a fall exceeds 500 mm, or when the gap between a platform and a structure (wall/machine) is greater than 180 mm. The top rail must be at least 1100 mm high.
Structural elements now undergo more rigorous load tests to ensure rigidity under real-world workforce conditions. This standard is part of the ISO 14122
When procuring the PDF, ensure you are buying the (DIN EN ISO 14122-3:2016-10), which is the most current active version and contains significant safety updates over the legacy 2001 edition.
The globally recognized standard for this is . Specifically, Part 3 (DIN EN ISO 14122-3) dictates the design, dimensions, and safety requirements for stairs, stepladders, and guard-rails. The standard distinguishes its access methods primarily by
Ensuring your machinery access meets the European Harmonized Standards , providing "presumption of conformity" with the Machinery Directive.
